In the Robotech Masters part of
the Robotech saga, once more the Earth is invaded
by Aliens. This time, the aliens are searching
for the remains of the SDF-1which was destroyed,
but has various pieces and remnants buried and
hidden which the Robotech Masters want to find so
desperately. The Robotech Masters are the
founders of Robotechnology which was a science
first created when Zor Prime a member of their
race stole the Invid Flower of Life and learned
how to develop its energy potential.

The Invid
Flower of life created a source of energy and
power that goes far beyond the means obtained by
nuclear reactions. With time such power corrupted
the Robotech Masters and Zor Prime attempted to
rid his people of the dangers imposed by this
means of energy. He sent a spacefortress to the
planet Earth in the hopes that its inhabitants
would use the science it allows for greater
purposes than that which his own people were now
famous for.

The Robotech Masters in their search for this
spacevessel's remants on the Earth recreate Zor
Prime in the form of a clone. He ultimately
befriends Dana Sterling a commander of a small
hovertank division from Earth's Robotech Defense
Forces. Zor Prime helps Dana lead a daring attack
on the Robotech Masters complexes which
ultimately destroys the Robotech Masters and
wipes their presence from the Earth. But this
attack caused remants of the SDF-1 space fortress
to escape into the air. The Invid Flower of Life
coated the planet and as a result the Invid an
even more agressive foe than the Robotech Masters
would soon be on their way to Earth to conquer it
and reclaim the Invid Flower of Life seeds
contained on the planet.

The Robotech Masters ravage the
Earth
lead by their elite Bioroid Terminator attack
units.

The Robotech Master Leadership triumverant,
composed of three cloned beings attempts
desperately to locate the remains of the SDF-1
for its protoculture production capabilities.
